Battery capacity is expressed in ampere-hours (Ah) and represents the total amount of energy stored in the battery pack that can be used to power a vehicle. To calculate battery capacity for an electric vehicle, you need to know the total energy stored in the battery pack (in kilowatt-hours, kWh) and divide it by the battery pack’s voltage.
Here’s the formula: Battery capacity (Ah) = Total energy (kWh) / Voltage (V) For example, if the total energy stored in the battery pack is 50 kWh and the voltage of the battery pack is 400 V, then the battery capacity would be: Battery capacity = 50 kWh / 400 V = 125 Ah
Battery capacity = 50 kWh / 400 V = 125 Ah Note: The actual usable capacity of an electric vehicle battery can be less than the theoretical capacity due to factors such as battery degradation and system inefficiencies. Determine the total energy stored in the battery pack.
